I have purchased probable close to 5 types of cleaning kits in my lifetime and I believe I have all of the parts minus one cleaning rod, and possible a few brushes.   I have learned that certain cleaning kits are better for certain firearms and others are mostly for traveling.  The clean kit i use the most is probable the Otis 556 cleaning kit but I still resort to a one piece cleaning rod.   Boresnakes are very usefull but they are caliber specific and with the Otis gun cleaning system you can basically have a multi caliber gun cleaning cord.   The only negative I find with the Otis kits is sometimes the parts fall out of the foam and you will have too many parts if you buy too many kits.  It’s best to learn the pros and cons of a system like this because you may want to consider getting the larger universal cleaning system.

When it comes to gun lubrication, I’m not sure if Otis is going to come out with a green cleaning system like M-Pro7 or Slip 2000.   I still  use several lubes and gun grease but the Otis gun cleaning kits are still in wide use in my gun collection.   I find this system to be excellent for the AR15 rifles as well as 22 caliber guns like my Ruger 10/22 and my Marlin 882 22magnum.   I still prefer a cleaning rod for bolt actions and my DS FAL rifle.   I personally have not noticed any difference in how well the items clean, but I do notice differences in the time it takes to actually clean a firearm.  Every firearm disassembles differently and I choose the gun cleaning system accordingly.
